Availability of Stainless Steel Grades

Availability of Stainless Steel Products

The tables below give an indication of the availability of stainless steel flat and long products. The intention is to give designers and specifiers some idea of how easy it will be to source their choice of grade and product form. The information has been created as a response to enquiries for rare grades which are difficult to source in small quantities.

Comments are invited on the tables. It is likely with such a large amount of information that there are some differences of opinion about the availability of some grades. If you want to make a comment on this table please email to ssas@bssa.org.uk.
